Method for making precise gestures with touch devices

Abstract

A method for operating a data processing system to implement a gesture on a touch enabled display is disclosed. The method causes the data processing system to determine a position of a contact object on the touch-enabled display as a function of time. The data processing system provides an offset indicating a distance through which a point shown on the display is to be moved in response to the determined position. The offset has a first value in a normal mode and a second value in a precise gesture mode. The value in the precise gesture mode is less than the value in the normal mode. The data processing system automatically changes from the normal mode to the precise gesture mode in response to changes in the determined position as a function of time. Exemplary changes utilize changes in direction or the speed of motion of the contact object.
